Will a quality USB cable make a difference....



Will a higher quality USB cable make a difference when being used between a storage device (bus-powered mobile drive) and a music server (w/o DAC), as opposed to those used between a source (iMac) and USB converter/DAC? Can anyone confirm an audible improvement?

Hi Ed,

Let me address the headphone part of what you were mentioning. Two channel speakers and headphones do things a bit differently. That doesn't necessarily mean one is better than the other. Speakers obviously have "real" soundstaging and imaging while headphones have "perceived" staging and imaging. While headphones can be highly resolving. As for timbre, tonal balance, transparency and coloring it's more or less a wash between them. There are too many variables. Especially with speakers that rely on a room's acoustics and speaker placement. I've heard enough two channel systems and headphones rigs (both low, mid and high fi) to know. I also know that a properly set up two channel system and headphone setup can both be extremely revealing of source and music.

The terrific thing about headphones is it's fairly easy to bring your entire setup with you. So, I've been to meets and listened to a wide variety of different gear. Systems that cost $100's, $1000's and even $10000's. Even headphones can cost in the $1000's. The top tier headphones sound amazing and rival very high quality speakers in many ways. I'm not talking about the cheap crappy things you get with your iPod here. Hyperbole aside, the Senn HD800 has been compared to speakers costing $40000. Your mileage may vary but you get the idea. My point is that high quality headphones are more than capable of detecting minute system changes. Some even better than certain speakers. So that's not the issue.

Moving on to having a laptop vs a tower, again I believe there are too many variables. I have directly compared my setup with other setups including analog and CD players. Let me say that I think, and others that have heard my system have said it's an excellent system.

Even with amplifiers, headphones amps can be of extremely high quality. I have two excellent amps capable of detecting system variances.

The last part, one you didn't mention, is, is my hearing up to the task? Without having to submit proof I'll say my hearing is probably at least on par with someone in their 40's. Although I think it's a bit better.

The thing is that although I've tried to hear significant differences in the two higher quality USB cables I have, I just can't say with certainty I hear any.

Peace,

Baka1969... sorry about the typo previously btw...

ok, so now I'm thinking that the first chance I get I'll do the easiest of two things: I'll serve my system with my laptop... last year's Dell... and see if I can discern a difference in its audio reproduction and whether or not, using the laptop as a server, I can hear differences in USB cords using the Dell laptop as a server. If you don't like Dells and Windows 7, I'm sure one of my buddies can find a late model Apple laptop for this experiment.

More to the point, I've asked one of my buddies to try to find someone who will loan me their headphone amp and headphones, equal to or better than your rig, and I'll do the same thing with a laptop. This might require some time and horse trading, but I'll see what I can do.

My hunch is that my system will be degraded considerably. Anyway, that's my operating theory. If that's invalidated, I'll be sure to pass it on as well because I will be able to free up some serious cash by selling my speakers, MacMini, and related cables (particularly the USB cables).

As I say, this might take a little time, but I'll at least do the laptop experiment within a couple of weeks (given my work schedule and family routines and scheduling). I don't have equivalent power cords to the Jellyfish... would Synergistic Research T3s and T2s be acceptable for this experiment?

I'll be sure to publish my impressions on Audiogon. I'll also bring in non-audiophiles (who won't know or understand what it is I'm doing) for their impressions as well.

:) listening,

Ed
Hi Ed,

Before you start let me know what your rig will be. I'll be curious if nothing else. I do have what many will consider as a top tier setup. My laptop is a Gateway WinXP. Not that should make enough of a difference. I've heard setups with win7.

Maybe it could be that the Nordost and Belden Gold USB cable just don't have significant differences? I haven't heard other name brand USBs yet so I won't speak of those.

I think/hope you'll enjoy the headphone syetem. It may not be the same as a two channel one, but can be pretty damn stellar. Let me know.

Since I grabbed some unknown red USB off a peg on the wall, I've been quite satisfied. This doesn't mean I wouldn't be more satisfied wth a $250 cable; what it does mean, is that I will never find out.
This got off track fast. My question was a simple one requiring a simple straight answer to; "can you detect an audible difference (improvement) with a higher quality USB cable when used between a STORAGE DEVICE (EXTERNAL DRIVE) AND A MUSIC SERVER (NO DAC)?". I've concluded no, simply based on the fact the data is not being transferred through a sensitive link between a digital source and DAC or converter. My example is the same as the music files being stored on/retrieved from a drive connected to a computer or on a network. It's not until that data is being transferred between the digital source (music player, streamer,...) and a DAC/converter that the cables quality comes into effect and becomes imperative. That's my unqualified, non-tech, take on this subject. If you have experience to the contrary I would like to hear.
